Bit of a newbie question I'm afraid.
A few weeks back my 1996 Pug 106 developed a vibration on braking, especially at speed. I took it to my local friendly garage (who are well recommended) and they said the front offside caliper was seized. They "unseized" it and replaced the pads (the old ones looked seriously knackered, burnt at the edges and crumbly).
For two weeks it was like having a new car, beautiful brakes. Now guess what. The same problem has returned. After reading a bit on the 'net I tried jacking up the front of the car and spinning the front wheels by hand. The near side makes a slight scraping noise and a reasonable push makes it turn once. The offside is worse, it takes quite a lot of effort to make it turn one free revolution and the scraping is really obvious.
Now I'm pretty sure this means the offside one is seized again, but what about the near side? Should there be any scraping sound at all? Should the wheels revolve more freely?
...and what do I do about it? I know you can service calipers, but I'm a little hesitant about doing that as my life depends on these two little bits of magic! Is it actually difficult or really straighforward[1]? Could it be a problem that servicing would'nt fix? Would it be worth me getting a professionally reconditioned pair and just replacing the old ones?
Any help much appreciated!
